We need to find the yards of ribbon that Elsa bought with her debit card.

The amount of ribbon that Elsa bought was 31 yards.

Initial amount which is present on the card is [tex]\$15[/tex]

Amount left after spending is [tex]\$12.83[/tex]

Amount spent on ribbon is [tex]15-12.3=\$2.17[/tex]

Converting to cents

[tex]2.17\times 100=217\ \text{cents}[/tex]

Cost of one yard of ribbon is [tex]7\ \text{cents}[/tex]

[tex]1\ \text{yd}=7\ \text{cents}\\\Rightarrow 1\ \text{cent}=\dfrac{1}{7}\ \text{yd}\\\Rightarrow 217\ \text{cents}=\dfrac{217}{7}=31\ \text{yd}[/tex]

The yards of ribbon that Elsa bought is [tex]31\ \text{yards}[/tex].

Answer: 5

Step-by-step explanation:

The coordinate of the midpoint M = 5

A line segment is defined as a measured path between two places. Line segments can make up any polygon's sides because they have a set length.

The figure given below shows a line segment ST, where the length of line segment ST  refers to the distance between its endpoints, S and T.

Given that M is the midpoint of ST

S______________M______________T

A midpoint is defined as in the middle of the line connecting two points a position known as a midpoint. A location in the middle of a line connecting the two points that are equally far from both points is the midpoint.

The endpoints of ST are -15 and 25.

So the midpoint between S and T is given by,

⇒ M = (25 - 15)/2,

⇒ M = 10/2

⇒ M = 5

Hence, the coordinate of the midpoint M = 5

   Sum of an arithmetic sequence is defined by the formula,

[tex]T_n=\frac{n}{2}[2a+(n-1)d][/tex]

Total length of the wooden boards will be [tex]14\frac{1}{6}[/tex] feet.

    It's given in the question,

Since, 1 inch = [tex]\frac{1}{12}[/tex] feet

Therefore, [tex]4[/tex] inch = [tex]\frac{4}{12}[/tex] feet

                             = [tex]\frac{1}{3}[/tex] feet

So, each stair is [tex]\frac{1}{3}[/tex] feet shorter than one below.

Now the sequence formed will be,

[tex]\frac{7}{2},[\frac{7}{2}-\frac{1}{3}],[\frac{7}{2}-\frac{2}{3}],......\frac{13}{6}[/tex]

[tex]\frac{21}{6},\frac{19}{6},\frac{17}{6}....\frac{13}{6}[/tex]

It's an Arithmetic sequence with common difference 'd' = [tex]-\frac{1}{3}[/tex] and first term 'a' = [tex]\frac{7}{2}[/tex] and nth term [tex]T_n=\frac{13}{6}[/tex]

If there are 'n' stairs, expression for the for the top stair of the arithmetic sequence will be,

[tex]T_n=a+(n-1)d[/tex]

[tex]\frac{13}{6}=\frac{21}{6}+(n-1)(-\frac{1}{3})[/tex]

[tex]\frac{13}{6}-\frac{21}{6}=-(n-1)\frac{1}{3}[/tex]

[tex]\frac{8}{6}=(n-1)\frac{1}{3}[/tex]

[tex]\frac{4}{3}=(n-1)\frac{1}{3}[/tex]

[tex](n-1)=4[/tex]

[tex]n=5[/tex]

Therefore, there are 5 stairs.

Now total length of the wooden boards = Sum of 5 terms of the sequence

                                                                    = [tex]\frac{n}{2}[2a+(n-1)(d)][/tex]

                                                                    = [tex]\frac{5}{2}[2(\frac{21}{6})+(5-1)(-\frac{1}{3})][/tex]

                                                                    = [tex]\frac{5}{2}[\frac{21}{3}-\frac{4}{3}][/tex]

                                                                    = [tex]\frac{17}{3}\times \frac{5}{2}[/tex]

                                                                    = [tex]\frac{85}{6}[/tex]

                                                                    = [tex]14\frac{1}{6}[/tex] ft

    Therefore, total length of the wooden boards will be [tex]14\frac{1}{6}[/tex] ft.

Answer:

d=14

Step-by-step explanation:

1d/6+2/3=1(d-2)/4

Find the L.C.M.

d+4/6=d-2/4

Cross multiply

4d+16=6d-12

Collect like terms

16+12=6d-4d

28=2d

Divide through by the coefficient of d

2d/2=28/2

d=14

Answer:

d = 20

Step-by-step explanation:

1/6*d + 2/3 = 1/4*(d - 2) do the multiplying

d/6 + 2/3 = (d-2)/4 now add fraction

d/6 + 2/3 to add these up we need to multiply 2/3 with 1/2 and it will be 4/6

d/6 + 4/6 = (d+4)/6

(d+4)/6 = (d-2)/4 cross multiply

4d + 16 = 6d - 24 add like terms

16 + 24 = 6d - 4d

40 = 2d divide both sides by 2

20 = d

Answer:

Step-by-step explanation:

The revenue function is given to you, it's just not given in equation form. In equation form, the function is

R(p) = p(120 - 4p)

If we are looking for the number of tickets that causes the revenue to be $0, we replace R(p) with 0 and solve for p.

0 = p(120 - 4p). That means, by the Zero Product Property, that

p = 0 or 120 - 4p = 0 which gives us, when we solve each one of those equations, that

p = 0 or

120 = 4p and

p = 30. The reasoning is the bold statement up above.

The equation we would use to determine the number of tickets needed to sell for the revenue to be $600 will be

600 = p(120 - 4p)

Answer:

-220

Step-by-step explanation:

2,300-1 then we go into the negatives 0- -2,300

so if -5 is further from 0 than -4 that means the larger number is further

Step-by-step explanation:

Hey did you find the answers to this? i really need it. im desperate!

1. The market is said to be in disequilibrium because there is a shortage of apartments on the market

2. The equilibrium quantity of the good or service will decrease if  demand decreases and supply decreases

3. The equilibrium price for this market is $20

4. It can be said that at a price level of $100 there is a  a shortage of 0.4 million units

Equilibrium is the point at which quantity demanded equal quantity supplied

The price at this point is referred to as the equilibrium price.

Above equilibrium, there is a surplus - quantity supplied exceeds quantity demanded. As a result of the surplus, price would fall until equilibrium is reached.

Below equilibrium, there is a shortage - quantity demanded exceeds quantity supplied. As a result of the shortage, price would rise until equilibrium is reached.

A decrease in demand would lead to a leftward shift of the demand curve. As a result, quantity and price decreases.  A decrease in supply would lead to a leftward shift of the supply curve. This leads to a decrease in quantity and an increase in price. Taking these two effect together, equilibrium quantity would decrease and there would be an indeterminate effect on equilibrium price

Equilibrium price is $20. This is because this is the price at which quantity demanded exceeds quantity supplied

There is a shortage because quantity supplied is less than quantity demanded

Shortage = 5.2 million - 4.8 million = 0.4 million

Answer:

x = [tex]\frac{5}{7}[/tex] , y = - [tex]\frac{3}{7}[/tex]

Step-by-step explanation:

Given 2 equal matrices then the corresponding elements in each matrix are equal, then

2x + y = 1 → (1)

x - 3y = 2 → (2)

Multiplying (1) by 3 and adding to (2) will eliminate y

6x + 3y = 3 → (3)

Add (2) and (3) term by term to eliminate y

7x + 0 = 5

7x = 5 ( divide both sides by 7 )

x = [tex]\frac{5}{7}[/tex]

Substitute this value into (1) and evaluate for y

[tex]\frac{10}{7}[/tex] + y = 1 ( subtract [tex]\frac{10}{7}[/tex] from both sides )

y = [tex]\frac{7}{7}[/tex] - [tex]\frac{10}{7}[/tex] = - [tex]\frac{3}{7}[/tex]

The proportion is solved and the number of games won by Ollie and Noelle over the weekend are 10 and 25 respectively

The proportion formula is used to depict if two ratios or fractions are equal. The proportion formula can be given as a: b::c : d = a/b = c/d where a and d are the extreme terms and b and c are the mean terms.

The proportional equation is given as y ∝ x

And , y = kx where k is the proportionality constant

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Given data ,

Let the proportion be represented as A

Now , the value of A is

Ollie won 2 games for every 5 games that Noelle won

So , the proportion is 2 : 5

Now , when Noelle won 10 games , Ollie won 4 games

And , when Noelle won 15 games , Ollie won 6 games

when Noelle won 20 games , Ollie won 8 games

when Noelle won 25 games , Ollie won 10 games

So , the difference of their winnings is now = 15 games

Hence , the number of games won by Ollie and Noelle over the weekend are 10 and 25 respectively
